Characterization of pollinated ‘Mitchell Diploid’ petunia flowers. (A) Pollen tube growth and petal wilting after pollination. Black rectangles overlaid on the style mark the pollen tube growth at 12, 18, and 24 hap (n = 4). Rectangle width is proportional to ± SD. (B) Ethylene production of unpollinated and pollinated styles. (C) Ethylene production of corollas from pollinated and unpollinated flowers (n = 6). Mean ethylene levels were used to create the line graphs, and the error bars represent ± SD. Vertical alignment of the time points are consistent for the entire figure.
